Ok, I've got CS5 and using a Mac. Save the Mac/Windows crud until AFTER we figure this out, then have at it! :P

Trying to save a file to enter in a challenge, optimizing for file, it does it's think, I hit save. Cool beans! BUT, when I go to uplift the photo, my computer tells me the file size on the disk image is 303 kb. Any ideas? This is SO frustrating! I"m marking progressive, not optimize, I'm making it RGB...everything is flattened...I'm out of ideas! (And of course I want it for tonight!)

Can someone please help? I've been trying to fixe this for 3 days and I refuse to enter a shot that's 500x500! Ugh!

Use "Save for Web & Devices". That gives you more options. When the pop up window opens adjust the jpg quality field (see right most circle in link below). While you are adjusting the value keep an eye on the file size in the lower left hand corner. Once you have the desired file size hit save.

That's what I've been doing, but the file size shown (lower left) when saved is NOT what the file size is when I go to upload. it's weird! I'm so frustrated. :( Thanks for the suggestion. :)

How much is the difference? Can you leave out the exif data a nd save a few k? Maybe compress it just a touch smaller and see if it then squeezes in?

Did you try to upload it?... if not, try. It will probably be accepted.

Kat, this doesn't help you I know, but I have exactly the same issue with CS5 (and as you know, I'm also a mac). I use optimise to file size, choose 300kb and then when try to upload here for a challenge it is always too big (by 2-5kb) I now just save it at 298 kb and that seems to do the trick. (I always leave out the exif)

Maybe it helps knowing it's not just you?

Sarah, it does help, but It is very odd. There has to be some stupid setting to change. Also, how do I make sure the EXIF is NOT being included?

Saved at 296kb and it is 303 kb on the 'puter, and NO, it won't be accepted by DPC, lol.

Kat there is a dropdown box underneath the convert to sRGB option. You can choose from the list there, what if anything you want to keep.

09/28/2010 11:58:58 PM · #10
That box? Mine is set to none, lol.
 09/29/2010 12:09:09 AM · #11
Hmm, sorry. Mine always seems to work if I save at 298.
 09/29/2010 12:11:51 AM · #12
I save at a maximum of 295Kb for this very reason, even in CS4.
 09/29/2010 12:12:03 AM · #13
This is normal for my luck, lol! Thanks all for trying. Hopefully we'll get it figured out (someday).
 09/29/2010 12:12:46 AM · #14
You are all making me feel better since I know it isn't just me! :P

save for web to get the file size indicated in the preview window:

optimize for file size (from the dropdown)
select progressive (not optimize)
leave embed profile unchecked

This will get you the file size you expect.

Choosing optimize for some reason makes the file about 5kb bigger than you expect.

Your guess is as good as mine as to why.

The file size listed in the (Mac) upload dialog box and Finder is a few (+ or -) KB's larger than the actual file size. That's the reason I suggested you try the upload.

really, that's weird, lol. Thanks all for the info. Sounds like we've all had to figure this out at some point or another. Sheesh!

Yep, just another echo of the same old song... the metadata does add some, and Ps only calculates the size of the data, so you always need to shave a bit off.
FWIW, *don't* check "progressive." That actually takes more space for the same end image quality. The difference with progressive is the image first displays a low-quality version, which gets "progressively" better as more data is downloaded. That was a good thing back when dialup was king, but it is not a good thing for your challenge entries, as the first version of your image the voter will see will be *bad*.

That's good to know about progressive. But why would the optimize option create a file larger than the optimize for file size entry when the embed check box is left blank?
